An early renaissance clavichord after following graphical evidence. this is not a copy but rather an atempt top build such an instrument using geometry and workbench knowledge as an organmaker in te 15th.c. would have perhaps done it. The compass is F, G, A, Bb, B, c-g2, a2, pitch is 520H and it weighs 4,5kg.
A similar larger version, slightly heavier, C/E - c3
Prices includes a flight case
A clavichord in the south-German tradition of around 1700. Fretted in the normal meantone manner with "d" and "a" unfretted, it is strung bichord throughout, from C-b° in brass and c'-c3 in soft steel. The case can be made of oak, walnut or cherry, the keys covered with either plum or box. Being a table instrument, it has no stand. C-c3
The Italians are made either of true cedar, cypress or maple. Each instrument is unique: its' drawing is preserved on the bottom. The key levers of beech are covered with European box or olive, but bone can also be had at an additional price of Euro 400.00. The wooden jacks are quilled with delrin or, at no extra cost with crow. The harpsichords are strung in brass; the desired pitch is fixed with the order. A transposing device for a semitone or two semitones can be had at an additional price of Euro 300.00 but instruments with enharmonic keyboards cannot have such devices.

The south-German harpsichord, although looking somewhat like an Italian, is quite a different instrument. It's bracing system with true inner rim and "A-frame" point towards the early fortepiano. Another important difference is the splaying of the jack guides, being farther apart in the bass than in treble. As a consequence, it has a more even tone with a stronger, purer treble. The visible case can be of almost any wood desired, the oak key levers covered with box or, as above, with bone. Like an Italian, it has no lid. Any reasonable compass between 4 and 5 octaves is possible at appropriate lengths.

Maria Grossmann south-German of claviorgan
Based on the south German instrument, a claviorgan is offered consisting of a chest organ onto which the above is laid and which is played from the harpsichord keyboard. Like all of my instruments, this is made only of solid wood and traditional materials with time-proven techniques. The case can be made of oak or walnut; the technical parts are of oak and lime.
This chest organ is in two parts, an upper containing the windchest, action and the pipes and a lower with the blower apparatus which can, at extra cost, be made as a foot driven feeder. The disposition I would suggest is: C,D-d3:
1. Stopped Diapason, divided at c1, the bass in true cedar, the treble as rohrflute of maple
The metal pipes are cone-tuned and secured against turning in their racks. They must remain in the chosen temperament. Both wooden stops are so adjusted that a wide range of temperments can be set, though obviously not a wide range of pitches. Normally, there is a transposing device from 415 to 440. For continuo purposes, this is sufficient. Such details must individually be discussed and have no import on the price.

I also make somewhat larger organs such as this I man. 10 rank chapel organ.
or this II man renaissance style organ now in the Johanneskirche in Zürich.
I restore historic organs such as this important instrument from Johann Viktor Gruol, 1809, the most important organmaker in the Duchy of Württemberg in the first half of the 19th.c.
I have devoted in part over 30 years to the study of Gruol's work and style.
I also make a two-manual version of the south German harpsichord, with or without 4'. The ones I have made have a dogleg front 8' which couples to the lower manual. A standard shove coupler would of course be possible. The one shown has no 4', but has two 8' ranks, both plucking to the left, on the lower, and the dogleg 8' plucking to the right on the upper manual. This instrument is veneered in walnut with a frame and panel lid, and is french polished. The inside is covered with hand marbled paper.
And this is the newest of this type being strung, also 3x8 but differently:
and with the keyboards, as yet unsawn, being fitted.

other German Harpsichords
At present , I offer a II-man instrument after Michael Miethke. This is based on the information to be gotten from the Berlin II-manual and the Swedish single. The Berlin instrument is much altered, but the case as such is not enlarged, and from the wrestplank, the original compass can be seen. Unlike many, I have decided that this instrument was probably originally strung with brass like the other two. With this in mind, I have "retro-designed" a II-manual to fit this case strung with brass scaling. Because a transposer is necessary, the lowest original note, FF has been left off to allow the keyboard to slide down. I have, like the Charlottenburg instrument, extended the compass to e3. To solve the problem of a viable 4' scale in brass, I have simply allowed the 4' to stop at c3 just as Miethke did. Otherwise, the instrument is identical to the original in framing, dimensions, and choice of woods. There are three ranks of jacks, in splayed box registers and a shove coupler.
II manual after Miethke: I manual 8'+4', II manual 8', shove coupler, 415-440, standard stand

6' muselar after Johannes Ruckers, 1623, C/E - c3, 410h, the case of
poplar or willow, keyboard bone covered. The original has a 14" scale,
thus was made for low pitch (±390). A 6' muselar usually has 13" scale,
thus for tuto punto = ±410h. Following Ruckers, I move the "magic
point" from 7" to 8" from the right edge and thus gain the standard 13"
A bentside spinet after the last extant instrument made by Albert Delin († 1771) in 1770. It is made of poplar or lime with an ebony covered keyboard exactly like those of Delin and has the original compass of C - e3 at 415Hz. Contrary to popular misconceptions, spinet from truely great makers like Delin were anything but cheap small alternatives to a "real" harpsichord.
The Flemish harpsichord, based on those of Albert Delin, is made of lime. The keys are covered with ebony or, as above, with bone. The compass is GG-e3 at 415Hz and a transposing device can be had for the additional DM 600.00, however, without the additional notes. It is strung in soft steel, brass and red brass.

The one manual harpsichord based on Andreas Ruckers instruments is made of willow. The compass is C/E - c3. There is one 8' and one 4,' and buff. The keys are covered with bone, the sharps of bog oak. The lid is in one piece, but can be made in two pieces for a slight fee.
Euro 10 300.00
The one manual harpsichord based on the Andreas I Ruckers 1640, Hotel du Croix, Namur, is also made of willow. The compass can be as on the original GG/BB-c3 at 415Hz or as a "petit ravalement" GG,AA-c3 with transposing device 415-440Hz. There is one 8' with two ranks of jacks and one 4' and buff. The keys are covered with bone, the sharps of bog oak. As on the original, the lid is in one piece.

The two manual Flemish harpsichord, based on the Ruckers instruments, is also a "petit ravalement" extending from GG - c3 or d3 with 2x8' + 4'. Two dispositions are possible: I - 8' + 4', II 8' + coupler or I - 8'+4', II - 8' dogleg

rose from H.Knopf for the last Donzelague
The French harpsichord is a copy of the instrument built in 1710 by Pierre Donzelague à Lion. Its case, too, is made of willow except for the bottom which is of fir. Its 5 octave keyboards are covered with ebony with bone-covered sharps. It has the standard "French" disposition of 8', 4', 8', buff and shove coupler. Because of its early date, this represents an instrument that was already in existence when Couperin and Rameau were writing.
